No batching or digest step, llms.txt, error code list, SLA or sub-processor list was found, and project tokens carry no scopes.\n\n**SuprSend.** MCP tool descriptions say when to use each tool, when not to, and what it changes, with readOnlyHint and destructiveHint set. No rate-limit page or 429 guidance.\n\n## Before you call either\n\n### MagicBell\n\n1. Ask the owner for a Project JWT from the dashboard's Project Auth page. The terms forbid accounts registered by automated methods\n2. Send `Idempotency-Key` with a UUID on `POST /v2/broadcasts`, and reuse it on a retry within 24 hours\n3. Stay under 500 requests a minute per IP. A 429 blocks the address for 60 seconds, so put many recipients in one broadcast\n4. Use a Project JWT for broadcasts, users, integrations and workflows, and a User JWT for one user's inbox, tokens and preferences\n5. Read delivery failures from `GET /v2/events` and the broadcast's `status`, since email, SMS and push go through providers the owner connects\n\n### SuprSend\n\n1. Pass an idempotency key on each trigger. It holds for 24 hours\n2. Start the MCP server with `--tools` set to read-only groups for production workspaces\n3. Register trigger tools with `--workflows=\u003cslug\u003e` for only the workflows you need. The default registers none\n4. Count each bulk record against the rate limit, and keep bulk calls to 100 records and 800 KB\n5. Treat management API responses as secrets. They include the workspace secret in plain text\n\n## Questions\n\n### Which is better for AI agents, MagicBell or SuprSend?\n\nSuprSend scores 72.6 (BB) on agent readiness against MagicBell's 58.8 (C), and leads in 6 of 7 scored categories. MagicBell leads on reliability.\n\n### Do MagicBell and SuprSend need an API key?\n\nBoth need an API key.\n\n### Can an agent call MagicBell and SuprSend without installing anything?\n\nYes.
